| 摘 要： | 磁矢量三维反演是近年发展起来的磁反演技术,能三维显示地下不同磁性体的空间展布,国外在磁性矿产勘查方面应用效果明显,开展该方法在铀矿勘查中的应用研究,可为寻找隐伏铀矿提供方法技术参考。文章简要介绍了磁矢量三维反演的基本理论,在此基础上选择龙首山铀成矿带中段新水井-芨岭地区的航磁数据分析其在碱交代型铀矿勘查中的应用效果,并利用二连盆地锡林浩特地区的航磁数据探索其在古河道型铀矿中的应用效果,探讨了将该技术应用于深部铀矿勘查的前景。结果表明:在碱交代型铀矿勘查中,磁反演结果可以较好地定位深部岩性界面这一有利找铀环境的空间位置;在古河道型铀矿勘查中,磁反演可以分辨出局部隆坳格局,缩小寻找深部古河道发育有利地段的范围。磁矢量三维反演可为寻找深部有利铀成矿环境提供地球物理参考,值得推广应用。

| Abstract: | Magnetization vector inversion is a newly developed technology in recent years,which can show the spatial distribution of different magnetic bodies underground,and has obtained positive application effect in magnetic mineral exploration abroad,but was seldom reported in the uranium exploration in China.In this paper,the basic theory of magnetization vector inversion was briefly introduced first.Then,Aeromagnetic data of Xinshuijing-Jingjiling area in the middle of Longshoushan uranium metallogenic belt were processed to show the application effect in the exploration of alkali metasomatic type uranium deposit.Aeromagnetic data of Xilinhot area in Erlian Basin were used to explore the paleochannel type uranium deposit,and the application vista of this technology in deep uranium exploration was discussed.The study showed that the magnetization vector inversion can effectively locate the deep lithologic interface which is the favorable space for uranium mineralization;discriminate the local uplift depression pattern and narrow the scope of deep paleo-channel distribution.Therefore,this method can provide a geophysical reference for the exploration of deep favorable uranium metallogenic conditions,and can be used more in uranium exploration. |
